Clover 9.0 whats new?
New Clover release is here!
This time I got around generating a better dataset for my network, it's a combination of 5k, 20k min nodes, some DFRC data.
Also net arch changed a bit, I added input bucket factoriser. Special thanks to @jw1912 (Bullet creator), for Bullet, easy to use for a very customisable trainer.
This release is ~40 elo behind Alexandria 8.1 in 40s+0.4s testing conditions.
Have fun and report any bugs!
Note: This release might be a bit weaker in FRC and DFRC mode, due to my data being around 50% standard chess, 50% DFRC data vs 100% DFRC data before.
